Title: Polyethylene terephthalate resin foamed product and its production
Inventor: MIYAMA OSAMU
IPC: B29C47/00
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To obtain a polyethylene terephthalate resin foamed product low in the density of the foamed product, having a good appearance, and high in the degree of closed pores, and to provide a method for producing the same. SOLUTION: This resin foamed product is produced by extruding and foaming a polyethylene terephthalate resin composition comprising a polyethylene terephthalate resin, a polyolefin resin and an epoxy group-containing polyolefin resin. The method for producing the polyethylene terephthalate resin foamed product comprises thermally melting the polyethylene terephthalate resin composition comprising the polyethylene terephthalate resin, the polyolefin resin and the epoxy group-containing polyolefin resin, impregnating the melted product with a foaming agent, and subsequently extrusion-foaming the impregnated product into a low pressure region.

Title: Vector control system for induction motor
Inventor: YAMAMOTO YASUHIRO
IPC: H02P23/14
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To reduce errors occurrences due to the steady component of an iron loss current component by subtracting steady iron loss current component flowing through an iron loss resistor approximated in parallel with the exciting inductance component of T-I type equivalent circuit from a primary current estimated value component, thereby simplifying the calculation of identical one-dimensional flux observer. SOLUTION: An iron current iRM, determined at an iron loss current operation section CIRM, is subtracted when a torque current component iT is determined from a primary current estimated value i1. The CIRM is approximated by the second power of flux or the 1.6-th power of frequency or provided with values in the form of table data of flux and frequency, by actually measuring iron loss so that the values can be read out. Flux observer can be estimation calculation, using an accurate torque current component where the iRM is corrected with respect to the iT. Since a feedback term is present inside the observer, the estimated primary current i1 converges to a value which is simply added with the iron current iRM and becomes equivalent to compensation of the estimated primary current with the iron current iRM component.

Title: Public telephone set
Inventor: ADACHI HIROYUKI
IPC: H04M17/02
Filed: 1989-10-20
Abstract: PURPOSE:To attain smooth communication in the pace of a calling-side by detecting a state where a remaining amount comes to a prescribed value and visually informing a user of the state. CONSTITUTION:When a control means 4 is informed that the remaining amount is less from a remaining amount detection circuit 2 while a public telephone set is used if a decided signal from a dial matrix 1 is previously received before a call is set, the control means 4 flickers an illumination lamp provided for a display unit 3 by an illumination lamp flickering circuit 11 instead of giving prescribed buzzer sound from a speaker 9 by an oscillation circuit 5. Consequently, only the calling-side (user) can learn the state where a system starts using the last coin or the last unit of a prepaid card (state where remaining amount comes to prescribed value). Thus, smooth communication is attained by the pace of the caller-side.

Title: Interface circuit
Inventor: KOSEKI TAKANORI
IPC: H03K17/00
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To provide the interface circuit in which malfunction is prevented, even when a noise signal in excess of a specified voltage and a specified pulse width is received. SOLUTION: Since a Zener diode 2 is connected to a cathode of a light- emitting element 55, a display device 57 is not lit, so long as a signal with a voltage in excess of the Zener voltage of the Zener diode 2 is not received. On the other hand, since a time constant circuit 61, consisting of a resistor 59 and a capacitor 60 and a comparator circuit 6, is connected to an output of a light-receiving element 56, a noise signal whose pulse width is shorter than a pulse width equivalent to a voltage in excess of a reference voltage of the comparator circuit 6 is not outputted from the comparator circuit 6. Since the Zener diode 2 and voltage divider resistors 3, 4 that generate a reference voltage of the comparator circuit 6 are replaceable, a noise signal with various voltages and various pulse widths is blocked.
